Abstract

A study on smell sensing and classification has been developed for a long time by many ways. Most of these have been focused on bad smells, when factors of bad smells were known chemically. Many gas sensors have been developed to detect specific chemicals. Our purpose is to make a new measurement system of smell gases and to apply it to classification of many gases. The proposed system has many sensors in a chamber and detects some chemicals at the same time. Smells data are transmitted to an A/D converter in a host PC which can be used to analyze data to classify the smells. The system must classify not only kinds of smells but also densities of them. In this paper, we develop the measurement system for multi-channel sensors made of metal-oxide semiconductors with power supply circuits.
